asus strix has 2 m.2 ports
(but as i mentioned before with TR boards, its not an issue- you can get one of those pci-e m.2 adapters for quite cheap for pci-e x16/8 and use it for your rest of m.2’s
it’s also a decent buy, tho it has definitly lower overclocking potential than the msi’s meg. *(tho keep in mind meg is the top mobo). In terms of phases no clue for the asus one’s. If you ask me. I would recommend going with middle options. Less junk on mobo the better. Take a look at the msi x399 gaming pro carbon vs asus strix one; and pick whichever you like more.
// Asus loads a lot of junk on their mobo’s.
